Study on the performance of piezoelectric pump for viscosity liquid pumping

2009 Symposium on Piezoelectricity, Acoustic Waves, and Device Applications (SPAWDA 2009), 2009
The simulation and experimental study to the pumping properties of the piezoelectric pump for different viscidity liquid are conducted. The influence of the different liquid viscosity to the driving performance of the piezoelectric pump is analyzed, and the fluid field pressure loss formula of the piezoelectric pump is obtained.

Development of a piezoelectric pump with unfixed valve

Journal of Micromechanics and Microengineering, 2022
Abstract Piezoelectric pump, driven by piezoelectric actuator, is one of the most promising micropumps in compact system. However, the application of piezoelectric pump is limited by the check valve, which is not efficient enough and needs careful fixation.

Design of a Piezoelectric Pump With Dual Vibrators

Sensors and Actuators A: Physical, 2017
Abstract The structures and working principles of a piezoelectric pump with dual vibrators are described in this paper. The output performance of the pump was analyses under different working modes. The experimental results demonstrate that changing the driving strategy can vary the performance. When the driving voltage is 60 V at 160 Hz, the maximum

A piezoelectric valveless pump with flexible actuators

Journal of Intelligent Material Systems and Structures, 2023
A piezoelectric valveless pump with flexible actuators (PVPFA) is proposed, which owns advantages of flexible driving, changeable flow direction and high output performance. The PVPFA is consist of three flexible actuators and a pump body. The direction of pumping fluid can be changed by setting different fluid medium volumes in the hydraulic ...

Development of serial-connection piezoelectric pumps

Sensors and Actuators A: Physical, 2008
To achieve high output performance at low actuation voltage, serial-connection multi-chamber piezoelectric micropumps (SCMCP micropumps) with cantilever valves were introduced. The SCMCP micropumps, which can be produced using conventional production techniques and materials, have a multi-layer circular planar structure.

Flexible fish-tail piezoelectric pump with bidirectional pumping characteristic

Review of Scientific Instruments
Dynamic valveless piezoelectric pumps are widely used in the field of microfluidics due to their advantages such as ease of miniaturization, absence of pump valve hysteresis, and lack of fine tubing within the pump chamber. However, all currently known dynamic valveless piezoelectric pumps can only achieve unidirectional liquid pumping, which limits ...

Research on the performance of a valveless piezoelectric pump with a herringbone bluffbody

Review of Scientific Instruments, 2023
Aiming to improve the output performance of a valveless piezoelectric pump, this article presents a valveless piezoelectric pump with a herringbone bluffbody. The bluffbody is herringbone shaped and distributed in a tapered chamber. The tapered chamber and the bluffbody create a large reverse resistance in the chamber, thus effectively mitigating the ...

[Pumping performance of a new piezoelectric pump for drug delivery].

Sheng wu yi xue gong cheng xue za zhi = Journal of biomedical engineering = Shengwu yixue gongchengxue zazhi, 2004
A novel double-chamber series piezoelectric pump has been presented and tested. The pump is a multi-layer circular planar structure, consisting of PMMA (polymethyl methacrylate) pump body, two PZT actuator membranes and three cantilever valves. The PZT actuators are driven at a phase difference of 180 degrees, which is equal to two one-chamber pumps ...
